The 4 class components on UNSAFE_componentWillReceiveProps converted: - FromNow, FireStats: state is a pure mirror of props -> getDerivedStateFromProps - Fires: split the derived state (getDerivedStateFromProps) from the URL- canonicalization side effect (componentDidUpdate, guarded by prevProps) so the side effect never runs inside the pure gDSFP - SelectionMap: marker is also locally draggable, so gDSFP would clobber a drag -> componentDidUpdate guarded on a real center/distance value change (no clobber, no setState loop), merged with the existing fit() Browser-verified: /fires count, fire detail + FromNow, active-fire URL canonicalizes to /fire/archive/:id, home SelectionMap renders stably (no render loop). No UNSAFE_ warnings remain from our code. REST smoke byte-identical.
